To all, 1.0790711 it rim/y concern:

Be it known that I, WI LLIAM POLAOK, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York,haveinvented certain new and useful Improvements in Container-Pumps; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in container-pumps.

The object of the invention is to provide a pump adapted to be appliedto a bottle or other container, whereby the liquid contents of the samemay be discharged therefrom into small-neck bottles or receptacleswithout Wasting or spilling.

Another object is to provide means whereby the quantity of liquid sodischarged may be ascertained.

A further object is to provide a pump of this character which will besimple, strong, and durable in construction, eificient in operation, andwell adapted to the use for which it is intended.

With these and other objects in view, the invention consists of certainnovel features of construction, combination, and arrangement 1 of parts,as will be hereinafter described and claimed.

in the accompanying drawings, Figure 1 is a side view of a bottle,showing the invention applied thereto and the manner of using the Fig. 2is a vertical sectional view of the same. Fig. 3 is a detail Verticalsectional view of the lower end of the pump-barrel, showing a modifiedconstruction of the piston-rod valve and showing the piston-rod andvalve in side elevation, the valve being shown open in full lines andclosed in dotted lines. Fig. 4: is a similar view of the same, showingthe piston-rod and Valve in section; and Fig. 5 is a detail sectionalview through the upper 5 end of the bottle-neck, showing the manner ofsecuring the pump in the bottle.

Referring more particularly to the drawings, 1 denotes the pump-barrel,which is here shown as a cylindrical metal tube of such size 3 as to fitwithin the mouth of abottle or other container. The lower end of thebarrel is reduced, as shown at 2, to form a valve-seat 3, upon which isloosely mounted a ball-valve 4. 1n the lower reduced end of the barrelare 5 formed recesses 5 to permit the entrance of liquid to the barrelshould said lower end of the same engage the bottom of the bottle.

Near the upper end of the barrel 1 is formed an annular series ofair-vents 6. On the other end of the barrel 1 is arranged a cap 7, saidcap being provided with an annular series of apertures 8, which areadapted to be brought into and out of alinement with the air-vents 6 inthe upper end of said valve to open and close the same. On the upper endof the cap is formed a radially-projccting annular flange 9, which isadapted to rest on and engage the upper end of the bottle, therebyclosing the same. In the upper end of the cap is formed acentrally-disposed aperture 10.

Arranged to reciprocate in the pump-barrel 1 is a hollow piston-rod 12,said rod passing through the aperture 10 in the top of the cap. On thelower end of the piston-rod 12 is secured a piston 13, and in said lowerend of the rod is formed a valve-seat 14, on which is loosely mounted aball-valve 15. Said valve 15 is arranged to act in conjunction with thevalve 4 in the lower end of the pump-valve, whereby when the piston-rod12 is rcciprocated in said valve water will be drawn therein on theupstroke of the piston, said water being forced into the hollowpiston-rod on the downstroke of the same. A continued reciprocation ofsaid piston-rod causes the liquid to be discharged from the upper end ofthe piston-rod through a spout 16 provided for this purpose. The upperend of the pistonrod is also provided with a head to facilitate theoperation of the same.

If desired, the piston-rod 13 may be provided with a measuring-scale 17,whereby the quantity of liquid forced into said piston-rod anddischarged therefrom may be ascertained.

In Figs. 3 and i of the drawings is shown aslightly-modiiied arrangementof the pistonrod valve. In this instance the lower end of the piston-rodis closed and above said closed end is formed an annular series ofradiallydisposed apertures 18. above which is secured a piston 19.Through the lower closed end of the piston-rod below the apertures 18passed a stop-pin 20, and on said lower end of the rod between thepiston 19 and the pin 20 is slidably mounted a valve 21. This valve 21is adapted to cover and uncover the apertures 18 on the up-and-downstroke of the pistonrod, thereby admitting and holding liquid in saidrod. This latter form of valve is used in connection with thepump-barrels for small narrow-mouth bottles in which the size of thepiston-rod is such as to prohibit the use of a ball-valve, as shown inFigs. 1 and 2 of the drawings.

By the use of a pump constructed as herein shown and described thecontents of a bottle or other container may be readily removed and thedesired quantities discharged into hottles or receptacles having verynarrow mouths withoutdanger of wasting said liquid. In operating thepump the spout 16 is inserted in the mouth or neck of a small bottle orreceptacle to be filled, as shown in Fig. l of the drawings, thuspreventing the spilling of any of the liquid. The flanged cap on theupper end of the pump-barrel forms a closure for the bottle orcontainer, thus taking the place of a stopper, and by turning said capslightly in one direction or the other the air-vents 6 will be closed,thus forming practically an air-tight closure for the bottle. In orderthat the pump-barrel and the ca 7 may be securely held in the bottle,springmetal clips 22 are provided, said clips being provided on theirlower ends with eyes or pas-' sages 23, through which is adapted to passa securing band or wire 24, which is passed around the neck of thebottle immediately below the flanged upper end of the same. The clips 22when swung upwardly into a locked position will engage the upper surfaceof the flange 9, thereby clamping the same upon the upper end of thebottle and firmly holding the cap and pump-barrel in place.

From the foregoing description, taken in connection with theaccompanyingdrawings, the construction and operation of the inven tionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle 0rsacrificing any of the advantages of" this invention.

Having thus described my invention, what A bottle or other container,and having at its upper end air-vents, a cap arranged on the upper endof the pum p-barrel to close said airvents and the mouth of thecontainer, means to hold said cap-plate and pump-barrel in place, avalve arranged in the lower end of the latter, a hollow piston-rodarranged to reciprocate in said pump-barrel, a valve adapted to open andclose the lower end of said pistonrod and a discharge-spout arranged onthe upper end of said rod, substantially as described.

2. A pump of the character described, comprising a bottle or containerhaving a flanged neck, a barrel adapted to be inserted into said bottleor container and having at its upper end air-vents, a flanged, aperturedcap arranged on the upper end of said pump-barrel to open and close theair-vents therein and to close the mouth of the container, spring-metalclips secured to the neck of the container and adapted to be engagedwith the flange of said cap to hold the same in place, a valve arrangedin the lower end of said pump-barrel, a hollow, graduated piston-rodadapted to reciprocate in said barrel, avalve to open and close theinner end of said piston-rod and a dischargespout arranged on the outerend of the same, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
